WWI German Postcard - Soldiers w Machine Gun in Trenches

This is a really nice WWI postcard. It is a sepia image with a light exposure but very interesting when one gives it a moment. Nine fellows in field uniforms with a belt fed machine gun. One is wearing a holster and one holding a grenade but the trench setting is interesting. They look to be congregating in front of an entrance to the trench which is heavily sandbagged on top. There is plenty of wood planking underfoot as the trenches did become hopeless quagmires when it rained and wood planking helped this considerably. Nice front line image the owner chose to develop into a postcard.
